I have got Windows to boot by resetting to 300MHz and shall get the patch.
Before the upgrade, I had been using a K6-2 300MHz with no problems - I
now want to transfer this to a second box to upgrade its Intel 166MMX.
My Windows is OSR 2.1, so presumably the patch will work.

The problem with shutting down Debian still remains. APM now works with
Windows, so I presume it must be something to do with the M'board as you
suggest. My knowledge is very limited - any suggestions as to where I
should go from here.

Many thanks for your help.
